## Summary

The procurement process, led by the buying organisation DESNZ, involves a contract variation titled "National Policy Statement - Appraisal of Sustainability & Habitats Regulations Assessment". This pertains to the industry category of research and development services and related consultancy services, classified under CPV code 73000000. The contract focuses on services across the United Kingdom, with specific delivery in London. The procurement method was selective, involving a call-off from a framework agreement. The tender stage concluded on 23rd April 2023, with the award status being active from 24th April 2023. The contract is valued at £254,387.50 and spans from 24th April 2023 to 31st October 2027.

This tender provides significant opportunities for businesses involved in environmental consultancy and regulation assessments, particularly those focusing on sustainability and habitats. Companies like AtkinsRéalis UK Limited, which has secured the contract, exemplify the kind of large-scale enterprises that can benefit from such government contracts. However, small and medium-sized enterprises (SMEs) may also find potential growth opportunities, as the procurement process highlights a suitability preference for SMEs. Firms with expertise in research and consultancy services, especially those equipped with capabilities in sustainability appraisal and regulatory compliance, would be particularly well-suited to engage in similar tenders in the future.

## Notice

A contract variation is required to cover the expanded scope and costs of the Appraisal of Sustainability (AoS) and Habitats Regulations Assessment (HRA) for an additional National Policy Statement (NPS). Both assessments, previously undertaken for the NPS on Nuclear Energy Generation (EN-7), are statutory requirements that now apply to the NPS on Fusion Energy (EN-8) as well. For this reason, additional work is required from the contract, without extending its duration. This is linked to Find a Tender Notice 2023-041424.
